ObjectiveTo investigate the association between immunoglobulin G （IgG）/immunoglobulin M （IgM） ratio and prognosis in patients with initially unresectable hepatocellular carcinoma （iuHCC） receiving TTP triple therapy with transcatheter arterial chemoembolization （TACE）， tyrosine kinase inhibitor （TKI）， and programmed cell death protein-1 （PD-1） inhibitors. MethodsA retrospective analysis was performed for the clinical data of 151 iuHCC patients who received TTP triple therapy in Department of Hepatobiliary Surgery， Guangxi Medical University Cancer Hospital， from November 2019 to December 2022， and according to IgG/IgM ratio， they were divided into high IgG/IgM group （IgG/IgM ratio >13.23） and low IgG/IgM group （IgG/IgM ratio ≤13.23）. The t-test was used for comparison of continuous data between groups， and the chi-square test was used for comparison of categorical data between groups. The Kaplan-Meier method and the log-rank test were used for survival analysis， and the Cox proportional hazards model was used to investigate the potential influencing factors for overall survival （OS）. ResultsThe 151 patients had a median OS of 26.7 months （95% confidence interval ［CI］： 19.8-not reached） and a median progression-free survival of 12.5 months （95%CI： 10.4 — 15.8）. The objective response rate was 83.4% and the disease control rate was 94.0%. There were no significant differences in baseline data between the high IgG/IgM group and the low IgG/IgM group （all P>0.05）. There was a significant difference in median OS between the high IgG/IgM group and the low IgG/IgM group （20.6 months vs not reached， P=0.016）. In both the high IgG/IgM group and the low IgG/IgM group， salvage hepatectomy was significantly associated with the improvement in OS （χ²=8.297 and 10.307， both P<0.05）. The multivariate analysis showed that high IgG/IgM ratio （hazard ratio ［HR］=1.799， 95%CI： 1.077 — 3.006， P=0.025）， baseline alpha-fetoprotein >400 ng/mL （HR=1.762， 95%CI： 1.017 — 3.050， P=0.043）， and BCLC stage （HR=2.265， 95%CI： 1.212 — 4.232， P=0.010） were independent influencing factors for OS. ConclusionHigh IgG/IgM ratio is associated with a poorer prognosis in iuHCC patients receiving TTP triple therapy， and salvage hepatectomy has a potential value in improving the prognosis of patients with a high IgG/IGM ratio.

ObjectiveTo observe the effects of modified Chaihu Shugansan on the calmodulin-dependent protein kinase Ⅱ（CaMKⅡ）/cAMP-response element binding protein （CREB） signaling pathway in the hippocampus and heart tissue of a rat model with myocardial ischemia and depression and explore the mechanism by which this formula prevents and treats coronary heart disease combined with depression. MethodsThe model of myocardial ischemia combined with depression was established by high-fat diet， intraperitoneal injection of isoproterenol （ISO）， and chronic unpredictable mild stress （CUMS）. A total of 108 SD male rats were randomly divided into normal group， model group， high （23.4 g·kg^-1）， medium （11.7 g·kg^-1）， and low （5.85 g·kg^-1） dose groups of modified Chaihu Shugansan， CaMKⅡ inhibitor （KN93） group， and KN93 + high， medium， and low dose groups of modified Chaihu Shugansan， with 12 rats in each group. From the first day of modeling to the end of modeling， drugs were administered once a day. In the seventh and eighth weeks， the KN93 group and the KN93 + high， medium， and low dose groups of modified Chaihu Shugansan were intraperitoneally injected with KN93 three times weekly. At the end of the eighth week， behavioral tests including sucrose preference， open field， and elevated plus maze were conducted. Electrocardiogram （ECG） lead Ⅱ changes were observed in each group of rats， and hematoxylin-eosin （HE） staining was performed to observe changes in heart tissue. Serum levels of triglycerides （TG）， total cholesterol （TC）， high-density lipoprotein （HDL）， low-density lipoprotein （LDL）， and lactate dehydrogenase （LDH） were measured by using an enzyme-labeled instrument. Creatine kinase （CK） and creatine kinase-MB （CK-MB） were detected by ultraviolet spectrophotometry， while serum monocyte chemoattractant protein-1 （MCP-1） was measured by enzyme-linked immunosorbent assay （ELISA）. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect mRNA expression of CaMKⅡ and CREB in hippocampal and heart tissue， and Western blot was performed to assess protein expression of CaMKⅡ， phosphorylated （p）-CaMKⅡ， CREB， and p-CREB. ResultsCompared to the normal group， the model group showed significant reductions in sucrose preference rate， total activity distance in the open field， number of entries into the center area of the open field， and percentage of entries into the open arms of the elevated plus maze （P<0.01）. The ECG showed ST-segment elevation， and HE staining showed serious degeneration of myocardial fibers， disordered arrangement， and infiltration of a large number of inflammatory cells. In addition， serum TC and LDL levels increased （P<0.01）， and HDL level decreased （P<0.01）. CK， CK-MB， LDH， and MCP-1 levels significantly increased （P<0.05， P<0.01）. The mRNA expression of CaMKⅡ and CREB and the protein expression of p-CaMKⅡ and p-CREB decreased in the hippocampal tissue （P<0.05， P<0.01）， but those increased in the heart tissue （P<0.01）. Compared to the model group， the high， medium， and low dose groups of modified Chaihu Shugansan showed improvements in these abnormalities. The KN93 group had reduced sucrose preference， total activity distance in the open field， number of entries into the center area of the open field， and percentage of entries into the open arms of the elevated plus maze （P<0.01）， as well as decreased serum CK， CK-MB， LDH， and MCP-1 levels （P<0.05， P<0.01）. KN93 also reduced ST-segment elevation， alleviated the degeneration degree of myocardial fibrosis， and lowered inflammatory cell infiltration. The mRNA expression of CaMKⅡ and CREB and the protein expression of p-CaMKⅡ and p-CREB in both the hippocampal and heart tissue were reduced （P<0.05， P<0.01）. The KN93 + high， medium， and low dose groups of modified Chaihu Shugansan showed further improvements in these abnormalities compared to the KN93 group. ConclusionThe modified Chaihu Shugansan exerts antidepressant and myocardial protective effects in rats with myocardial ischemia and depression， possibly related to bidirectional regulation of the CaMKⅡ/CREB signaling pathway， with the high-dose modified Chaihu Shugansan showing the best effects.

Objective:To evaluate the diagnostic performance of 64Cu-prostate specific membrane antigen (PSMA)-Q compared with 18F-FDG in patients with advanced prostate cancer and to analyze the radiation dosimetry of 64Cu-PSMA-Q. Methods:This study was an open-label, single-arm, self-controlled diagnostic evaluation trial. A total of 29 patients (age 58-87 years) with pathologically confirmed advanced prostate cancer in the Affiliated Hospital of North Sichuan Medical College from September 2023 to December 2023 were included. All patients underwent both 64Cu-PSMA-Q PET/CT and 18F-FDG PET/CT examinations. McNemar test was used to compare the detection rates of 64Cu-PSMA-Q PET/CT and 18F-FDG PET/CT for primary lesions, lymph node metastases, and bone metastases. Mann-Whitney U test was applied to compare differences in SUV max and tumor-to-background ratio (TBR) between 64Cu-PSMA-Q PET/CT and 18F-FDG PET/CT. Radiation dosimetry of 64Cu-PSMA-Q PET/CT imaging was performed using OLINDA/EXM 2.1 (adult male model) in 9 patients. Results:Primary lesions were detected in 21 patients. 64Cu-PSMA-Q PET/CT demonstrated a detection rate of 95.2%(20/21) for primary lesions, which was significantly higher than that of 18F-FDG PET/CT (66.7%(14/21); χ2=6.00, P=0.031). Detection rates of lymph node metastases were 65.5%(19/29) for 64Cu-PSMA-Q and 55.2%(16/29) for 18F-FDG, with no significant difference ( χ2=3.00, P=0.250). Similarly, detection rates of bone metastases were 72.4%(21/29) for 64Cu-PSMA-Q and 65.5%(19/29) for 18F-FDG respectively ( χ2=2.00, P=0.500). TBRs on 64Cu-PSMA-Q PET/CT were significantly higher than those on 18F-FDG PET/CT across primary lesions (8.3(2.2, 13.3) vs 2.3(1.0, 5.5); Z=7.16, P=0.002), regional lymph node metastases (4.9(1.4, 8.3) vs 1.7(0.9, 4.0), Z=189.34, P=0.001), and bone metastases (18.7(4.5, 26.9) vs 5.1(2.1, 9.7); Z=24.83, P=0.003). No significant difference in TBR was observed for distant lymph node metastases ( Z=1.49, P=0.135) or benign lesions ( Z=0.91, P=0.558). The whole-body effective dose of 64Cu-PSMA-Q was (28.200±1.590)μSv/MBq among the 9 patients analyzed, with no adverse events related to the tracer observed. Conclusion:64Cu-PSMA-Q is a promising novel PET imaging agent with potential clinical utility for diagnosing prostate cancer and supporting clinical decision-making.

Objective:To investigate the utilization of inpatient service and influencing factors among pneumoconiosis patients in Chongqing within one year, and to provide a reference basis for the formulation of relevant policies by health management departments.Methods:From October 2020 to October 2023, a multi-stage cluster random sampling method was adopted to select 2002 patients with confirmed pneumoconiosis as the research subjects. A questionnaire survey was conducted on their basic information, inpatient service utilization within one year, treatment for pneumoconiosis-related symptoms, and choice of medical service institutions. Chi-square test and logistic regression were used for statistical analysis.Results:All 2002 pneumoconiosis patients were male, with 40.16% (804/2002) aged 46-55 years old, and 83.32% (1668/2002) currently residing in rural areas. The monthly income of the patients was 833 (167, 2000) yuan, and 22.03% (441/2002) had no income. 30.97% (620/2002) of the patients spent more than 5001 yuan per year on treatment for pneumoconiosis, and 14.64% (293/2002) had debts of more than 5001 yuan. 42.06% (842/2002) had no work-related injury insurance. 21.68% (434/2002) of the patients self-assessed their health status as very poor or poor. The one-year inpatient rate of the patients was 51.25% (1026/2002), and the total inpatient time within one year was 18 (10, 51) days. The inpatient expenses were 6000 (1000, 16625) yuan. Through univariate analysis, the one-year inpatient rates of pneumoconiosis patients were statistically significantly different among different age groups, current employment status, annual household income levels, types of pneumoconiosis, stages of pneumoconiosis, presence or absence of work-related injury insurance, whether receiving minimum living allowances and social assistance related to pneumoconiosis, and different segments of self-assessed health status ( P<0.05). Patients with stage Ⅲ pneumoconiosis, those who received social assistance and minimum living allowances related to pneumoconiosis had higher one-year inpatient rates ( P<0.05), with OR values of 3.893, 1.859, and 2.589, respectively. Conclusion:The utilization of inpatient service by pneumoconiosis patients is influenced by demographic characteristics, social support, and disease factors. It is necessary to enhance the occupational disease diagnosis and treatment capabilities of primary health institutions, build a multi-level social support network, and ensure that patients can conveniently access medical services.

Objective To analyze the composition characteristics and biological functions of tumor cell subpopulations in glioblastoma(GBM)through multi-transcriptomics sequencing technology,and explore the hypoxia characteristics and spatial localization features of the mesenchymal-like(MES-like)tumor cell subpopulation in GBM and the influence on malignant biological behaviors.Methods Multi-transcriptomics sequencing data,including single-cell RNA sequencing(scRNA-seq)data(18 patients),bulk RNA sequencing(bulk RNA-seq)and spatial transcriptomics(ST)data of GBM,were employed to define cell subpopulations in GBM,and Gene Ontology(GO)and Gene Set Enrichment Analysis(GSEA)were utilized to analyze their functions.The proportions and locations of cell subpopulations in bulk RNA-seq data were evaluated with BayesPrism deconvolution.Immunofluorescence assay was conducted for verification on 12 paraffin samples of GBM from patients who visited the neurosurgical department of our hospital from 2015 to 2023 and met the pathological diagnostic criteria for GBM(10 males and 2 females,at an average age of 53.50 years and a median age of 54.50 years).pySCENIC was applied to predict specific transcription factors of tumor cell subpopulations.Results Tumor cells in GBM were highly heterogeneous,and could be mainly divided into 4 subpopulations:astrocyte-like(AC-like),neural progenitor-like(NPC-like),oligodendrocyte progenitor-like(OPC-like)and MES-like.Differential gene analysis found that the MES-like tumor cells highly expressed vascular endothelial growth factor A(VEGFA),adrenomedullin(ADM),N-myc downstream regulated 1(NDRG1),insulin like growth factor binding protein 5(IGFBP5),and A-kinase anchoring protein 12(AKAP12)(P<0.001).pySCENIC transcription factor prediction found that the high-active transcription factors of the MES-like tumor cells were AT-rich interaction domain 3A(ARID3A),FOS like 2,AP-1 transcription factor subunit(FOSL2),endothelial PAS domain protein 1(EPAS1),CCAAT enhancer binding protein delta(CEBPD),and CCAAT enhancer binding protein beta(CEBPB)(P<0.05).GO and GSEA enrichment analyses found that the MES-like tumor cells were enriched in hypoxia-related pathways,especially the pathway of cell responses to hypoxia levels(NES=2.437,P<0.001).BayesPrism deconvolution showed that the MES-like tumor cells mainly existed in PAN(Pseudopalisading cells around necrosis)and perinecrotic zone.Immunofluorescence assay confirmed CD44+(CD44 antigen)MES-like tumor cells were mainly located in hypoxia areas with highly expression of hypoxia inducible factor 1 subunit alpha(HIF1α)(P<0.01).Multivariate Cox regression analysis indicated that the MES-like tumor cells were significantly correlated with the adverse prognosis of GBM patients(HR=1.71,95%CI:1.38～2.11,P<0.001).Conclusion Tumor cells in GBM are of highly heterogeneity.They could be mainly divided into 4 subpopulations:AC-like,NPC-like,OPC-like and MES-like.MES-like tumor cells,mainly locating in PAN and perinecrotic zone,are characterized by hypoxia,which can promote the malignant progression of GBM.

OBJECTIVE To analyze the correlation between styloid process related parameters and symptoms in patients with styloid process syndrome.METHODS A retrospective study was conducted on the 3D reconstruction CT results of the styloid process in 68 patients diagnosed with styloid process syndrome who visited the Department of Otolaryngology Head and Neck Surgery,the Second Affiliated Hospital of Xi'an Jiaotong University from January 2010 to December 2024.The relationship between parameters such as styloid process length,angle,distance from styloid process tip to pharynx,and specific symptoms in patients with styloid process syndrome was analyzed.RESULTS Among 68 patients with styloid process syndrome,44 had unilateral symptoms and 24 had bilateral symptoms.The length of the styloid process on the symptomatic side of patients with unilateral symptoms(3.86±0.16)cm was significantly longer than that on the asymptomatic side(2.98±0.17)cm(Z=-2.191,P=0.028);The length of the styloid process on the side with severe symptoms in patients with bilateral symptoms(3.98±0.37)cm was also significantly longer than that in patients with mild symptoms(3.37±0.15)cm(t=2.448,P=0.024).Patients with styloid process syndrome mainly present with pharyngalgia(64.71%,44/68).There were no significant differences in the length,inclination angle,anteversion angle,and distance between the styloid process tip and the pharynx among those with unilateral pharyngalgia(n=29),bilateral pharyngalgia(n=15),and non pharyngalgia(n=24)(P>0.05).However,among the 68 patients with styloid syndrome,12 had calcification of the styloid hyoid ligament,while 56 did not.The incidence of unilateral pharyngalgia was significantly higher in patients with calcification of the styloid hyoid ligament than in patients without calcification(66.7%vs.35.7%,χ2=3.909,P=0.048).CONCLUSION The severity of symptoms in patients with styloid process syndrome is related to the length of the styloid process,and those with calcification of the styloid hyoid ligament are more likely to experience pharyngalgia.

Congenital orofacial cleft, the most common birth defect in the maxillofacial region, exhibits a wide range of prognosis depending on the severity of deformity and underlying etiology. Non-syndromic congenital orofacial clefts typically present with milder deformities and more favorable treatment outcomes, whereas syndromic congenital orofacial clefts often manifest with concomitant organ abnormalities, which pose greater challenges for treatment and result in poorer prognosis. This consensus provides an elaborate classification system for varying degrees of orofacial clefts along with corresponding diagnostic and therapeutic guidelines. Results serve as a crucial resource for families to navigate prenatal screening results or make informed decisions regarding treatment options while also contributing significantly to preventing serious birth defects within the development of population.
